Chapter 7.6, Problem 13E

To determine

To find: The admission price.

Answer to Problem 13E

When the pass is used, the amount of the admission price is $\$10.4$ .

Explanation of Solution

Given information: For a child, the regular admission price to a zoo is $\$13$ . With a special pass, the admission price is discounted $20\%$ .

Calculation:

The regular admission price to the zoo is $\$13$ and the discount percent is $20\%$ .

To find the discounted admission price, the discount amount should be subtracted from the regular admission price.

Now, when the pass is used, the admission price is,

  $=$ Regular admission price $-$ Discount amount $\mathrm{......}(1)$

Where the discount amount = Regular admission price $\times$ Discount percent

  $\begin{array}{l}=\$13\times 20\%\\ =\$13\times \frac{20}{100}\\ =\$13\times 0.20\\ =\$2.6\end{array}$

Let’s find the admission price with the help of equation $(1)$ ,

  $\begin{array}{l}=\$13-\$2.6\\ =\$10.4\end{array}$

Hence, When the pass is used, the amount of the admission price is $\$10.4$ .
